TOPIC 1: GAMETOGENESIS
7 Questions • 8.1% of Exam • This topic covers the processes involved in the formation of male and female gametes.
QUESTION 1
What are male gametes?
Answer: Sperm.
Rationale: Sperm are the male gametes, which are reproductive cells produced by males. These haploid cells contain half
the genetic material of a diploid organism and are responsible for fertilizing the female gamete, the ovum.
QUESTION 2
What are female gametes?
Answer: Secondary oocytes.
Rationale: Female gametes are mature female reproductive cells. In humans and many other animals, the female gamete
is the secondary oocyte, which is released from the ovary during ovulation.
QUESTION 3
Process of spermatogenesis
Answer: Spermatogonia (germ cells)-- Primary spermatocyte (2n)-- Meiosis I occurs-- Secondary
spermatocytes 2 of (n), Meiosis II occurs-- Spermatids 4 of (n)-- Spermiogenesis (production of sperm)
Rationale: Spermatogenesis is the process by which male gametes, sperm, are produced from germ cells called
spermatogonia. This process begins with diploid spermatogonia (2n) differentiating into primary spermatocytes, which then
undergo meiosis I to produce two haploid secondary spermatocytes (n).
